 # vcpkg_extract_source_archive
 
-Extract an archive into the source directory.
+Extract an archive into the source directory. Deprecated in favor of [`vcpkg_extract_source_archive_ex`](vcpkg_extract_source_archive_ex.md).
 
 ## Usage
 ```cmake
diff --git a/docs/maintainers/vcpkg_extract_source_archive_ex.md b/docs/maintainers/vcpkg_extract_source_archive_ex.md

+# vcpkg_extract_source_archive_ex
+
+Extract an archive into the source directory. Replaces [`vcpkg_extract_source_archive`](vcpkg_extract_source_archive.md).
+
+## Usage
+```cmake
+vcpkg_extract_source_archive_ex(
+    OUT_SOURCE_PATH <SOURCE_PATH>
+    ARCHIVE <${ARCHIVE}>
+    [REF <1.0.0>]
+    [NO_REMOVE_ONE_LEVEL]
+    [WORKING_DIRECTORY <${CURRENT_BUILDTREES_DIR}/src>]
+    [PATCHES <a.patch>...]
+)
+```
+## Parameters
+### OUT_SOURCE_PATH
+Specifies the out-variable that will contain the extracted location.
+
+This should be set to `SOURCE_PATH` by convention.
+
+### ARCHIVE
+The full path to the archive to be extracted.
+
+This is usually obtained from calling [`vcpkg_download_distfile`](vcpkg_download_distfile.md).
+
+### REF
+A friendly name that will be used instead of the filename of the archive.
+
+By convention, this is set to the version number or tag fetched
+
+### WORKING_DIRECTORY
+If specified, the archive will be extracted into the working directory instead of `${CURRENT_BUILDTREES_DIR}/src/`.
+
+Note that the archive will still be extracted into a subfolder underneath that directory (`${WORKING_DIRECTORY}/${REF}-${HASH}/`).
+
+### PATCHES
+A list of patches to be applied to the extracted sources.
+
+Relative paths are based on the port directory.
+
+### NO_REMOVE_ONE_LEVEL
+Specifies that the default removal of the top level folder should not occur.
+
+## Examples
+
+* [bzip2](https://github.com/Microsoft/vcpkg/blob/master/ports/bzip2/portfile.cmake)
+* [sqlite3](https://github.com/Microsoft/vcpkg/blob/master/ports/sqlite3/portfile.cmake)
+* [cairo](https://github.com/Microsoft/vcpkg/blob/master/ports/cairo/portfile.cmake)

+# vcpkg_from_git
+
+Download and extract a project from git
+
+## Usage:
+```cmake
+vcpkg_from_git(
+    OUT_SOURCE_PATH <SOURCE_PATH>
+    URL <https://android.googlesource.com/platform/external/fdlibm>
+    REF <59f7335e4d...>
+    SHA512 <abcdef123...>
+    [PATCHES <patch1.patch> <patch2.patch>...]
+)
+```
+
+## Parameters:
+### OUT_SOURCE_PATH
+Specifies the out-variable that will contain the extracted location.
+
+This should be set to `SOURCE_PATH` by convention.
+
+### URL
+The url of the git repository.
+
+### SHA512
+The SHA512 hash that should match the archive form of the commit.
+
+This is most easily determined by first setting it to `0`, then trying to build the port. The error message will contain the full hash, which can be copied back into the portfile.
+
+### REF
+A stable git commit-ish (ideally a tag or commit) that will not change contents. **This should not be a branch.**
+
+For repositories without official releases, this can be set to the full commit id of the current latest master.
+
+### PATCHES
+A list of patches to be applied to the extracted sources.
+
+Relative paths are based on the port directory.
+
+## Notes:
+`OUT_SOURCE_PATH`, `REF`, `SHA512`, and `URL` must be specified.
+
+## Examples:
+
+* [fdlibm](https://github.com/Microsoft/vcpkg/blob/master/ports/fdlibm/portfile.cmake)
